Digestive System Facts
• Unfortunately, germs can stick to food dropped
on the floor in less than five seconds.
• Every time you lick a stamp, you consume 1/10 of
a calorie.
• If your stomach didn't produce a new layer of
mucous every two weeks, it would digest itself.
• People eat more popcorn when watching a sad
movie as compared to a happy one.
• Food can get to your stomach even if you are
hanging upside down.
• The small intestine is about four or five times
larger than the large intestine.
• The small intestine can be as short as 4.6 m (15
feet) to as long as 9.8 m (32 feet).
• And here is a picture of a pig’s digestive system:
Digestive System Card Sort
• 1st: Sort the cards as a table group. You can
use your notes in this round.
• 2nd: Sort the cards as a table group. You
cannot use your notes in this round.
Digestive System Card Sort Answers
• Ingestion: esophagus, getting food into our bodies
• Digestion: stomach, breaking food down into
smaller pieces
• Absorption: villi, getting nutrients in the
bloodstream so cells can use them
• Elimination: getting rid of waste products
• Note:
– Mouth could be ingestion or digestion
– small intestine could be digestion or absorption
– Large intestine could be absorption or elimination

Digestive System Stories
Page
Today’s Plan
• Complete the White Bread Challenge to
demonstrate the importance of one of the
parts of the digestive system
• Create a digestive system story to further
understand what exactly happens in the
digestive system
White Bread Challenge
Now we will review a few important
ideas
• Pay really good attention during the review or
the next assignment you have will be difficult.
Review
• Remember that the digestive system’s
functions happen in this order:
– Ingestion (eating)
– Digestion (smashing the food down)
– Absorption (getting the nutrients from the food)
– Elimination (getting rid of the waste)
Review
• The food goes through the digestive system’s
organs in this order:
– Mouth
– Esophagus
– Stomach
– Small intestine
– Large intestine
Digestive System Stories
• By yourself or in a group of up to three people,
you will write a story about a piece of food’s
journey through the digestive system.
• You have to pick a certain type of food and write
the story from the point of view of the food.
– Example: I’m a slice of pepperoni pizza from Papa
Johns. One day I was created in a very hot oven and
delivered to some hairy dude’s house. After licking his
lips, the hairy man chomped down on my crust! …
Digestive System Stories
• Your food has to go through ingestion, digestion,
absorption, and elimination. You must mention
each part of the body it travels through and
what happens in each part of the body.
• Your story should be creative and the info on
the digestive system must be accurate.
• Near the end of the hour we will read several
stories and vote on the best one. The winners
will get a prize next time they are in class.
Complete your homework!!
•Homework is
due on
MONDAY.
